From face to surface- optimised processes and increased understanding of fragmentation

Reference number
Coordinator Luleå tekniska universitet - Institutionen för samhällsbyggnad och naturresurser
Funding from Vinnova SEK 5 470 000
Project duration September 2013 - February 2017
Status Completed
Venture The strategic innovation programme for Swedish mining and metal producing industry - SIP Swedish Mining Innovation

Purpose and goal

SIP STRIM the Strategic Innovation program for the Mining and Metal Mining aims to strengthen the mining sector competitiveness and contribute to sustainable development. This project has significantly reduced production costs, improved resource efficiency and improved characterization of the ore.

Expected results and effects

The Face-to-Surface project is focused on "more efficient and competitive processes, equipment and methods", "resource efficiency" and "Increased energy efficiency" in the STRIMs agenda. The project has demonstrated how significant savings can be achieved by optimizing fragmentation. The influence from rock mass Properties, mainly structural information such as cracks, fracture, voids, etc. have been used to optimize the charging and blasting operation. Loading and transport efficiency have been increased for both surface and underground operations.

Planned approach and implementation

The project Face-to-Surface has been implemented as two individual projects, one surface project and one underground project with essentially different applications. This broad approach and the significantly different technical conditions have not been ideal from a project implementation perspective, and have brought a lot of extra administrative work. The research work carried out in production environments, however, meant that the results have industrial relevance and have a shorter way to applications.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
